When Nottinghamshire County Council needed to upgrade its 20-year-old noise monitoring equipment, it made sense to choose two of the latest high performance 63x series sound level meter kits from previous supplier, Casella - leading global specialist in occupational health and environmental risk management solutions

Nottinghamshire County Council is the Minerals and Waste Planning Authority tasked with administering planning applications for Council-owned developments including new roads and schools.

David Collins, Project Engineer, Landscape & Reclamation and Environment & Resources comments: “The ability to implement noise measurements is an essential requirement of my role at the Council. Our department delivers a range of acoustic services such as assessing noise levels at the site of a submitted planning application and preparing acoustic reports like Noise Impact Assessments or Baseline Noise Surveys. We also provide general guidance on noise issues.”

He continues: “One of our outdated sound level meters was a Casella model so we knew they were a trusted brand with a reputation for delivering cost effective yet reliable solutions. Reliability is essential as we carry out unattended noise measurements. The 63x meets all our key requirements as it can be used to take long and short term environmental measurements and 1/3 octave band analysis plus calibration can be evidenced to ensure any noise data is accurate and will stand up to scrutiny.”

As well as the sound level meter, each kit includes an environmental case, outdoor mic protection, batteries and charger. The 63x was also chosen because it meets required British Standards (BS61672-1 Electroacoustic Sound Level Meters) and can measure standard environmental noise parameters (LAeq, L90, L10, etc).

Nottinghamshire County Council received detailed training in the use of the 63x from Casella. The company even sent a demonstration model so staff could familiarise themselves with the kit ahead of the half day course. David adds: “The training was very helpful in helping us understand the capabilities and benefits of the software which enables us to quickly download, analyse, save and export data.

The Casella 63x sound level meter kits have already been used for a baseline noise survey on a £16million ring road improvement scheme by Nottingham County Council. The project entailed setting up the equipment at 16 properties along a five mile stretch of the ring road for a period of 24-hours at a time. Further short term monitoring was implemented at five properties.

They have also helped with noise assessment of land owned by the Council for potential residential development. Measurements were taken at various positions around the site which is currently agricultural land on a 24 / 7 basis to determine the noise exposure categories in accordance with the superseded guidance in Planning Policy Guidance 24 (PPG24) as requested by the Local District Authority Planners.

Baseline noise surveys have been conducted at three schools in Nottinghamshire on behalf of the Council’s property team. Data was used to inform noise impact assessments for the site.

David concludes: “The 63x is very simple to operate in comparison to older sound level meters and we are particularly impressed with the easy to use menus, settings and analysis software. Casella is a reputable supplier of well proven noise monitoring equipment and I wouldn’t hesitate to recommend them to other Councils across the UK.”
